Our display is clean and modern, offering you the ability to search for and select multiple related products at once. With our drag and drop feature plus instant search you won't be stuck for time either, when curating the products for cross selling. The designs of the products cross selling row are the same as the collection page - an important feature that makes your website look clean and professional.

Super fast and super reliable, but how?

Typically, the main reason for a Shopify app to be slow or to have downtime is because the content delivered to your customers depends on the server of the app. Currently, every cross selling & up-selling app on Shopify works this way... except ours. This means we don't have to pay for very large servers, and can offer the app at a much lower price point. Cross selling - by is built to handle scale, because 100% of the app's content that your customers receive is delivered from Shopify servers which are highly reliable and are build for Black Friday & Cyber Monday traffic.

But why is cross selling so important?

Cross selling is the simple practice of selling additional products or services that are related to the original item that a customer is looking for. When you set up a shop, you want to sell as many products as you can. If you can sell your whole stock at once, better for you. But if you don't have the right techniques to present your products, your customers may buy as little as they can, and because you are not physically present to convince your customers to buy more, you need the help of automated services to do the work for you. This is why our cross selling app is your best ally: we offer the cross selling facilities you need, providing you special tools, like the popups and facility to install as we do not require you to do any sort of coding or pasting snippets.

Go Fetch! pet food

Very useful app for my type of business. I use the popup to suggest three or four specific add-on items, such as treats when dog food is purchased. I also am setting up eight related items per cross-sell row beneath the product descriptions. I have already moved several units of slow sellers this way in just a few days. Definitely good ROI for me. My theme was not one that worked without a custom install. Patrick (the app dev) kindly worked with me over a few days to get everything customized to my satisfaction. 5+ star app!

The app doesn't look at all like in "view example store" I checked setting and couldn't find how to configure the look like in "view example store". If I missed something, i'll gladly retry. Thanks

I am very happy about customer service. When I tried this app I found out I need a new function to create different carousel with different default product in order to cross sell different products with the same design. Since I have to do the same steps again an again and it is really time consuming on my part. I asked Patrick if there is anyway or solution that we can do it faster. Then I got an email told that he spent the day working on a feature for that. What a wonderful service!!!
